UPVC Windows has revolutionized the game of windows and door systems. It is a topic of interest for all architects, developers, and constructors who want to take up better and innovative projects. This article offers in-depth information about UPVC Window System, its types, uses, advantages and disadvantages and comparison with alternate materials used in window systems.
What are UPVC Window Systems?
UPVC (unplasticised polyvinyl chloride) is a form of plastic which is durable, rigid, and strong. It provides a solid foundation for doors and window frames. It is BPA-free, which means that it cannot be contaminated and does not have any toxic characteristics.
UPVC vs PVC Windows
Architects prefer UPVC over PVC for window systems for its unique properties:
- Does not warp in extreme temperatures.
- It is recyclable.
- It is chemical erosion-resistant.
- Maintaining UPVC windows and doors is easy
- It is not too heavy on the pocket.
- It is long-lasting.
Doors and Windows are the underrated stars of an amazing architectural design. Constructors and architects give a lot of thought in their designing and planning. Windows not only provide ventilation and light but also enhances the aesthetic appeal of a building.
Types of UPVC Window Systems:
There are many types of UPVC Window Systems. In this article, we have narrowed down some of the most widely used categories.
UPVC Windows #1: Casement Windows
Casement windows are attached to their frame at the side by one or more hinges. The air leakage rate is very low in Casement Windows. They are excellent for ventilation. They trap the heat with their effective sealing.
UPVC Windows #2: Awning Windows
Awning windows are hinged at the top. They open outward. They offer protection from rain and sunlight and also provide proper ventilation. Most awnings are made from UPVC which makes them highly durable.
UPVC Windows #3: Slider Windows
Slider windows slide to open sideways. They offer proper ventilation and light. Sliding or Slider Windows are great space-saving solutions for buildings. They come in two and three-way sliders. A variety of styles and colour options are available in Sliding UPVC Window Systems
UPVC Windows #4: Single-Hung and Double-Hung Windows
One of the most common types of window systems, single hung and double hung windows come with movable sashes. In single hung sash windows, the top sash is fixed and the bottom sash is operable. In double sash windows, both the frames are operable. Double and Single Hung Windows are easy to clean and offer ample sunlight and ventilation.
UPVC Windows #5: Bay Windows
Architects simply love Bay windows as they help create beautiful angles and projections on a building. Light can enter through different angles. They come with a side window that can be opened to allow the entry of air. The window sills are ideal for keeping plants or placing a window seat.
UPVC Windows #6: Picture Windows
Picture windows are ideal for buildings in which airflow is not a matter of consideration. These are large glass expanses, usually occupying the centre portion of the all. They offer ample sunlight and view. Choosing the right UPVC material with the correct thickness, quality, and efficiency is important, as the entire window system depends upon it. UPVC Window Systems are preferred by architects, constructors, and designer to Aluminium Windows or Wooden Windows for many reasons.
UPVC Window Systems Advantages:
Durability and sturdiness
UPVC Doors and Windows are highly durable. They have a better and longer life than the conventional Solid Wood Windows or Aluminium Windows. UPVC Window Systems are resilient too. They are termite and temperature resistant. Their lifespan is very long compared to traditional materials.
Sustainable fenestration solution
UPVC is 100% recyclable. Towards the end of its life, it can be converted, reprocessed, and repurposed into other products. It is environment-friendly and weather-proof.
UPVC Doors and Windows are not affected by fungus. They are immune to rotting, warping, or rusting. They are naturally resistant to pollution, chemical, and water. Carrying and handling UPVC is easy as it is very light-weighted.
UPVC is a great thermal insulator. It does not allow the outside heat to enter the building and the inside cooling to escape outside. In adverse climatic conditions, where the temperature is extremely chilling, UPVC Window Systems trap the warmth inside the room; allowing a comfortable living.
Furthermore, UPVC Doors and Windows offer sound insulation as well. If you are living in an area with high noise pollution such as near the airports, highways, etc. UPVC is the right choice for you. However, UPVC has some disadvantages as well.
UPVC Window Systems Disadvantages:
Compared to solid wooden doors and windows, UPVC looks less sophisticated and refined. The former has a better aesthetic appeal. UPVC has a limit to customization and personalization as it is manufactured for the masses with more focus on the functionality and durability.
Due to their lightweight, UPVC Window systems often get sagged and sashed. The frames might rupture over time. Aluminium Windows are much stronger in this respect. But to overcome this obstacle a Mild steel rod runs through the cross-section of the window to make it stronger and rigid.
How to choose the right UPVC Window System?
- UPVC Profile: The profile or the frame of the window is extremely important as the efficiency and durability of the window primarily depends upon it.
- Glass Unit: UPVC Window Systems come with double-glazed windows. Double glazing comprises two glass sheets that have an air layer between them. This technology increases the sound insulation capacity of the window.
- Seals: Seals are responsible for the tight-fitting of the sash to the window frame. They are changed quite often as they are more prone to wear and tear on regular use.
- Window furniture hardware items: These include the most important components of the UPVC Window Systems. Window handles, locks, interlocks, etc. make up the hardware of UPVC Windows. LGF SYSMAC, Hafele, Hettich, etc are some major brands that offer a wide range of architectural hardware components. They provide hardware items and window fittings for all types of UPVC Window Systems. Superior quality window and door locks are essential for the security of the building.
- Additional accessories: Mosquito nets, insect screens, blinds, etc. are the add ons that enhance the aesthetics and functionality of the windows.
- Price also plays an important role while choosing the right UPVC Window Systems: Price range of UPVC Windows in India is from Rs 300/ sq ft to Rs 1200/sq ft. The material quality, finishes, brands, colours and many other factors play a role in deciding the price of UPVC Window Systems.
Challenges with UPVC Windows and their preventive measures:
1. Weather damage
India is a country with extreme weather conditions. The central and western parts experience extreme heat. The northern and eastern parts have low-temperature conditions. The southern part remains hot and humid all throughout the year. Monsoons are terrible in most regions of the country. To avoid the damage caused by varied weather conditions, its manufacturers came with an innovative solution, i.e. to add Titanium dioxide to the UPVC Window Systems.
Use of Titanium dioxide in UPVC Window Systems:
UPVC profiles are outdoor products. Therefore, weather damage is a common issue that might compromise the durability and longevity of the entire window system. Manufacturers add Titanium Dioxide (TO2) to the UPVC compound so as to develop weather resistance in the windows and doors profile. This chemical absorbs the UV light and protects the polymer from degradation, fading, and discolouration. TO2 also protects the windows from heat and other weather damages; thus, protecting the overall structure and durability of the entire building.
2. Different wind pressure conditions
Another major problem faced by UPVC Window Systems is the ability to bear the wind pressure at different heights. UPVC Windows were originally made for low-rise buildings that do not have to withstand too much wind pressure. However, the material gained overnight popularity and began to be used widely for all types of buildings.
But as discussed earlier, the material tends to sag and sash over time. When exposed to high wind pressure, the process gets quicker.
Use of Mild Steel Rods in UPVC Window Systems
To overcome this challenge, the UPVC manufacturing companies came up with yet another creative idea. A mild steel rod is inserted in the UPVC cross-section. This rod makes the entire profile ten folds stronger and powerful enough to withstand extreme wind pressures without getting damaged.
